# Survey & Research Glossary (2026)

An authoritative reference for survey methodology and customer-experience metrics — NPS, CSAT, CES, Likert scales, response bias, sampling, and more. Each entry includes definition, formula where applicable, example, and 2026 benchmarks.

## Metrics

### Net Promoter Score (NPS)

Net Promoter Score (NPS) measures customer loyalty by asking how likely customers are to recommend a product or service on a 0-10 scale.
https://spaceforms.io/glossary/nps

### Customer Satisfaction (CSAT)

Customer Satisfaction (CSAT) measures how satisfied customers are with a product, service, or interaction on a 1-5 or 1-10 scale.
https://spaceforms.io/glossary/csat

### Customer Effort Score (CES)

Customer Effort Score (CES) measures how much effort a customer expended to complete a specific interaction, typically on a 7-point agree/disagree scale.
https://spaceforms.io/glossary/ces

### Survey Response Rate

Response rate is the percentage of invited respondents who completed (or at least started) a survey.
https://spaceforms.io/glossary/response-rate

### Survey Completion Rate

Completion rate is the percentage of survey starters who finished all questions.
https://spaceforms.io/glossary/completion-rate

### Employee Net Promoter Score (eNPS)

eNPS adapts NPS to measure how likely employees are to recommend their employer as a place to work.
https://spaceforms.io/glossary/enps

### Customer Lifetime Value (CLV / LTV)

Customer Lifetime Value (CLV or LTV) is the total revenue (or gross profit) a business expects to earn from a customer over the entire relationship.
https://spaceforms.io/glossary/customer-lifetime-value

### Churn Rate

Churn rate is the percentage of customers (or revenue) lost during a given period, typically reported monthly or annually.
https://spaceforms.io/glossary/churn-rate

### NPS Trend

NPS trend tracks how Net Promoter Score changes over time, surfacing directional shifts that a single-period score cannot reveal.
https://spaceforms.io/glossary/nps-trend

### Top-Box Scoring

Top-box scoring reports the percentage of respondents who selected the highest rating (top box) or top two ratings (top-2-box, T2B) on a scale.
https://spaceforms.io/glossary/top-box-scoring

### Net Easy Score (NES)

Net Easy Score (NES) measures the ease of a customer interaction by subtracting the percentage of 'difficult' ratings from 'easy' ratings on a 5- or 7-point ease scale.
https://spaceforms.io/glossary/net-easy-score

## Scales

### Likert Scale

A Likert scale is a survey rating scale with ordered response options (typically 5 or 7 points) used to measure attitudes, agreement, or frequency.
https://spaceforms.io/glossary/likert-scale

### Five-Star Rating

A five-star rating is a 1-5 ordinal scale, typically displayed as star icons, used for product reviews, app stores, and lightweight CSAT.
https://spaceforms.io/glossary/five-star-rating

### Semantic Differential Scale

A semantic differential scale presents two opposing adjectives at the ends of a 5- or 7-point scale and asks respondents to mark their position between them.
https://spaceforms.io/glossary/semantic-differential

## Concepts

### Promoters (NPS)

In NPS, promoters are respondents who score 9 or 10 on the 'likely to recommend' question — your strongest advocates.
https://spaceforms.io/glossary/promoters

### Detractors (NPS)

In NPS, detractors are respondents who score 0-6 on the 'likely to recommend' question — unhappy customers at high churn risk.
https://spaceforms.io/glossary/detractors

### Passives (NPS)

In NPS, passives are respondents who score 7 or 8 — satisfied but unenthusiastic customers vulnerable to competitive offerings.
https://spaceforms.io/glossary/passives

### Anonymous Survey

An anonymous survey collects responses without any personally identifying information.
https://spaceforms.io/glossary/anonymous-survey

### Employee Engagement

Employee engagement is the emotional commitment employees have to their organization and its goals.
https://spaceforms.io/glossary/employee-engagement

### ACSI (American Customer Satisfaction Index)

The ACSI is a national economic indicator of customer satisfaction with the quality of products and services available to US household consumers.
https://spaceforms.io/glossary/acsi

### Voice of Customer (VoC)

Voice of Customer (VoC) is a systematic program for collecting, analyzing, and acting on customer feedback across every touchpoint and channel.
https://spaceforms.io/glossary/voice-of-customer

### Onboarding Survey

An onboarding survey collects feedback from new customers (or employees) during the first 30-90 days to identify activation friction and predict retention.
https://spaceforms.io/glossary/onboarding-survey

### Exit Interview / Exit Survey

An exit interview collects feedback from customers or employees at the moment of departure to understand why they're leaving and to identify systemic issues.
https://spaceforms.io/glossary/exit-interview

### Customer Journey Mapping

Customer journey mapping is the practice of visualizing the end-to-end experience a customer has with a brand across stages, touchpoints, channels, and emotions.
https://spaceforms.io/glossary/customer-journey-mapping

## Methodology

### Sample Size

Sample size is the number of respondents needed for survey results to be statistically meaningful at a given confidence level and margin of error.
https://spaceforms.io/glossary/sample-size

### Margin of Error

Margin of error is the range within which the true population value likely falls, given the sample size and confidence level.
https://spaceforms.io/glossary/margin-of-error

### Confidence Interval

A confidence interval is the range within which a true population parameter is expected to fall, at a specified confidence level.
https://spaceforms.io/glossary/confidence-interval

### Pulse Survey

A pulse survey is a short, frequent survey (3-5 questions) used to track sentiment over time.
https://spaceforms.io/glossary/pulse-survey

### Product-Market Fit Survey (PMF)

A PMF survey measures whether a product has achieved product-market fit, typically via Sean Ellis's 'very disappointed' test.
https://spaceforms.io/glossary/pmf-survey

### Kano Model

The Kano model categorizes product features by their impact on customer satisfaction: must-haves, performance, delighters, indifferent, reverse.
https://spaceforms.io/glossary/kano-model

### Van Westendorp Pricing

The Van Westendorp Price Sensitivity Meter uses four questions to identify the range of acceptable prices for a product.
https://spaceforms.io/glossary/van-westendorp

### In-App Survey

An in-app survey is a short survey delivered inside a digital product, typically triggered by user behavior or milestone events.
https://spaceforms.io/glossary/in-app-survey

### Micro-Survey

A micro-survey is a very short survey (1-3 questions) designed to minimize respondent effort and maximize completion.
https://spaceforms.io/glossary/micro-survey

### Random Sampling

Random sampling is a probability sampling method where every member of the target population has an equal, known chance of being selected.
https://spaceforms.io/glossary/random-sampling

### Stratified Sampling

Stratified sampling divides the population into mutually exclusive subgroups (strata) and samples randomly within each, ensuring proportional or oversampled representation.
https://spaceforms.io/glossary/stratified-sampling

### Cluster Sampling

Cluster sampling divides the population into naturally occurring groups (clusters) and randomly selects entire clusters, then surveys all or some members within them.
https://spaceforms.io/glossary/cluster-sampling

### Convenience Sampling

Convenience sampling recruits whoever is easiest to reach — website visitors, email-list subscribers, social-media followers — and is the dominant approach in commercial surveys despite its limitations.
https://spaceforms.io/glossary/convenience-sampling

### Longitudinal Survey

A longitudinal survey collects data from the same respondents (or population) at multiple points in time to measure change.
https://spaceforms.io/glossary/longitudinal-survey

### Cross-Sectional Survey

A cross-sectional survey collects data from a population at a single point in time, providing a snapshot of attitudes, behaviors, or outcomes.
https://spaceforms.io/glossary/cross-sectional-survey

### Panel Survey

A panel survey repeatedly surveys the same pre-recruited group of respondents over time, enabling within-person change analysis.
https://spaceforms.io/glossary/panel-survey

### Mixed-Methods Research

Mixed-methods research combines quantitative (numeric, statistical) and qualitative (interview, open-text) data within a single study to triangulate findings.
https://spaceforms.io/glossary/mixed-methods-research

### 360-Degree Feedback

360-degree feedback collects performance and development input on an individual from multiple perspectives: manager, peers, direct reports, and self-assessment.
https://spaceforms.io/glossary/360-feedback

## Bias & Errors

### Response Bias

Response bias is any systematic tendency of respondents to answer questions inaccurately, either intentionally or unconsciously.
https://spaceforms.io/glossary/response-bias

### Acquiescence Bias

Acquiescence bias is the tendency of respondents to agree with statements regardless of their actual opinions.
https://spaceforms.io/glossary/acquiescence-bias

### Central Tendency Bias

Central tendency bias is the tendency of respondents to avoid extreme options on a rating scale, clustering toward the middle.
https://spaceforms.io/glossary/central-tendency-bias

### Leading Question

A leading question is one whose wording suggests a particular answer, biasing the respondent toward it.
https://spaceforms.io/glossary/leading-question

### Social Desirability Bias

Social desirability bias is the tendency of respondents to answer in ways they believe will be viewed favorably by others.
https://spaceforms.io/glossary/social-desirability-bias

### Recall Bias

Recall bias is a systematic error caused by respondents inaccurately remembering past events, behaviors, or feelings — usually worsening with elapsed time.
https://spaceforms.io/glossary/recall-bias

### Selection Bias

Selection bias is a systematic error arising when the people included in a survey differ from the target population in ways that affect the outcome.
https://spaceforms.io/glossary/selection-bias

### Nonresponse Bias

Nonresponse bias occurs when the people who do not respond to a survey differ systematically from those who do, on the variable being measured.
https://spaceforms.io/glossary/nonresponse-bias

### Order Effect

Order effect is the bias introduced when the sequence of questions or answer options influences responses.
https://spaceforms.io/glossary/order-effect

### Priming Bias

Priming bias is the influence that an earlier stimulus (question, image, word) has on how a respondent interprets or answers later questions.
https://spaceforms.io/glossary/priming-bias

## Compliance

### HCAHPS (Hospital Consumer Assessment)

HCAHPS is the CMS-mandated standardized patient experience survey for US hospitals.
https://spaceforms.io/glossary/hcahps

## Question Types

### Open-Ended Question

An open-ended question allows respondents to answer in their own words with free-text input rather than choosing from pre-defined options.
https://spaceforms.io/glossary/open-ended-question

### Closed-Ended Question

A closed-ended question presents respondents with a fixed set of answer choices to select from.
https://spaceforms.io/glossary/closed-ended-question

### Ranking Question

A ranking question asks respondents to order a set of items by preference, importance, or priority, producing ordinal data on relative preference.
https://spaceforms.io/glossary/ranking-question

### Matrix Question

A matrix question (or grid question) displays multiple sub-questions sharing the same response scale in a table, letting respondents rate many items efficiently.
https://spaceforms.io/glossary/matrix-question

### Demographic Question

Demographic questions collect background information about respondents (age, gender, role, company size, region) to enable segmentation and weighting.
https://spaceforms.io/glossary/demographic-question

### Branching Logic

Branching logic (conditional logic) routes respondents to different follow-up questions based on their previous answers, creating personalized survey paths.
https://spaceforms.io/glossary/branching-logic

### Skip Logic

Skip logic is a form of branching that omits irrelevant questions for a respondent based on previous answers, shortening survey length and improving completion.
https://spaceforms.io/glossary/skip-logic
